From wikipedia:
Following graduation, Einstein could not find a teaching post. After almost two years of searching, a former classmate's father helped him get a job in Berne, at the Federal Office for Intellectual Property,[13] the patent office, as an assistant examiner. His responsibility was evaluating patent applications for electromagnetic devices. In 1903, Einstein's position at the Swiss Patent Office was made permanent, although he was passed over for promotion until he "fully mastered machine technology".[14] With friends he met in Berne, Einstein formed a weekly discussion club on science and philosophy, jokingly named "The Olympia Academy". Their readings included Poincaré, Mach, and Hume, who influenced Einstein's scientific and philosophical outlook.[15] During this period Einstein had almost no personal contact with the physics community.[16] Much of his work at the patent office related to questions about transmission of electric signals and electrical-mechanical synchronization of time: two technical problems that show up conspicuously in the thought experiments that eventually led Einstein to his radical conclusions about the nature of light and the fundamental connection between space and time.[14][15]
1901.
Yes, in Switzerland.
patent clerk
Albert Einstein was a theoretical physicist, not an inventor (although he did once work in a patent office). While he did not invent things himself, his theoretical work was essential for a number of inventions that other people invented, including the atomic bomb and the laser.
He never worked for the patent office in his life. He has many patents to his name but the patents came form work in his laboratories.
Although Einstein is most famous for his work in physics, he did invent and patent a refrigerator. It was his only patented invention.
In 1901 he accepted a position in the patent office where most of his work is said to come from. His free time gave him a lot of thinking time.
Albert Einstein went to collage for physics and then became a patent clerk in Zurich. He worked 6 days a week and could work on his theory of relativity along with doing this mentally unchallenging job.
Albert Einstein did his work in labs.
His fame was gained when he came to america, to work on the famous "E=MC squared" Albert Einstein did a lot of his important early work while he was a patent clerk in an office in Bern, Switzerland. This includes his work on General relativity and the energy properties of light, i.e. photo-electric effect. It would be an oversimplification to say that the only work that made him famous was the work he did while in Bern.
Albert Einstein mostly worked in New Jersey.
Albert Einstein did not work on the atomic bomb.
